THE TWO OLDEST TREES 



Examples: Take a tree thirty feet in 

 circumference it will be ten feet in di- 

 ameter; the distance from the heart to 

 the outside of the bark, or one-half the 

 diameter, would be five feet or sixty 

 inches. Supposing you have found the 

 average number of rings to the inch to be 

 twenty, then you have the age of the tree 

 1200 years. 



When measuring a stump you can 

 determine the exact number of rings as 

 you can stop where the bark begins; if 

 the tree is standing and you wish to make 

 an exceptionally correct comparison, I 

 would get the exact diameter of the tree 

 by measuring the bark on both sides, and 

 the result deducted from the outside cir- 

 cumference will be the diameter of the 

 body of the tree. This can be easily done 

 and without harm to the tree by using a 

 small pointed steel properly ruled off. 

 Most barks of trees are easily penetrated 

 and without harm to the tree.
